Mind Sear animation

Few days ago I recognized a strange thing about mind sears animation. And I could have sworn it was not like this the day before:

Mindsear "ripples" (for the lack of a better word) out from your target. Now I always get the riplles for the first 2-3 ticks, but the last 2 are just the beam animation without the aoe animation. Does this happen to you guys too? As I said I could have sword that I had the aoe animation for all the 5 seconds way before?
